The plug accepts AT&T 735, 735A, and Belden 735A1 cable — a specific triaxial-style cable group, not RG-59 or RG-6. ## Crimp Termination — Shield and Contact in One Step Both the shield and the centre contact are crimp-terminated. For field termination, the cable prep must match the AT&T 735 / Belden 735A1 group dimensions — the ferrule ID and the centre contact crimp barrel are sized for that specific cable jacket and dielectric diameter. ## 3 GHz Bandwidth, 75 Ohm — Where It Fits The 3 GHz maximum frequency covers the L-band and most of the S-band, which is enough for base station RF distribution, GPS signal splitting, and broadcast video up to 3G-SDI. The 75 Ohm impedance is non-negotiable for these signal paths — a 50 Ohm cable or connector would create a mismatch and degrade return loss.","metaTitle":"Amphenol 282118-75 1.0/2.3 Plug, 75 Ohm, 3 GHz, Crimp","metaDescription":"Amphenol 282118-75 1.0/2.3 plug, 75 Ohm, 3 GHz max frequency.
